    Friedländer's 6.6 m (22 ft) diameter Halladay "wind motor" was supplied by U.S. Wind Engine & Pump Co. of Batavia, Illinois. The 3.7 kW (5 hp) windmill drove a dynamo at ground level that fed electricity into a series of batteries. The batteries powered various electrical tools and lamps, as well as a threshing machine.

    This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locked to the speed of the power grid and cannot speed up. So large forces are developed in the hub, gearbox, and generator as the power grid pushes back.

  6. Darrieus wind turbine - Wikipedia

    en.wikipedia.org/wiki/Darrieus_wind_turbine

    The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from wind energy. The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft or framework. The curvature of the blades allows the blade to be stressed only in tension at high rotating speeds. There are several ...

  7. Wind power - Wikipedia

    en.wikipedia.org/wiki/Wind_power

    Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. [181] A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power , and other systems to start ...
